How to sew a sweatband into a hat?

My hat has a sweatband and i think it's a leather band but i'm not sure. My question is: What kind of thread should i use to sew the sweatband and hat back together? The sweatband is coming loose and i want to fix it without using glue, so i need to know what thread to use. Thanks. My hat has hushpuppy inside the top. In the first picture i've attached you can see the band is detached, and i don't know if you can, but in the second picture you should be able to see parts of the logo. Thanks again
